which is unprovided with an internal strengthening-strip is preferablyalso provided with. a heavy rail Gr, woven in with each section of thefabric forming the side, if desired. The metallic ribbons which are usedthe fabric are preferably arranged in pairs (0 b, which are oppositelyand alternately arranged, as shown. This arrangement imparts a muchgreater strength and rigidity to the fabric than where the slats arewoven together by Wires, and inasmuch as the ribbons-have acomparatively wide bearing upon the slats they will not cut into thelatter, as is the case with wires. The end strips of each section of thefabric are securely held in place by bending over the ends ofthe-ribbons to form double retaining-loops, as shown,

A weak point in the structure of most boxes of this, general characteris at the corners of the adjoining sides of the case. These beingsubject to rough usage are apt to be split or broken, and wherereinforced by strengthening-pieces the latter-are easily knocked off. To overcome this difficulty, the present structure is provided withcorner-braces of the following construction: H represents metallicanglestrips, preferably formed of sheet metal and adaptedto extend alongthe vertical corners of the box. At their ends these strips are split atthe angle, so as to form separate sections 0 and (Z, which may be bentover the edge rails and secured to the inner face of the box. Inasmuchas the top and bottom rails are of'greater thickness than the bodyportion of the fabric and as this increased thickness projects outward,it is necessary to split the brace H far enough from the ends to passaround these thickened rails. After passing outside of said thickenedrails the end sections 0 and cl are bent over the top to cross eachother on top of the inner strengthening-strip E and are lapped down thesides of said strip a short distance, so as to both securely fasten thestrip in position and prevent danger of the ends of the brace beingcaught and stripped off. The metallic angle-braces formed and arrangedas above described may be secured to the body portion of the fabric Toall whom it may concern/.-

Be it known that I, GUs'rAvE A. SoHwAN- BECK, a citizen of the UnitedStates, residing at Detroit, in the county of Wayne and State ofMichigan,

have lnvented certain new and useful Improvements in Cases, of which thefollowing is a specification, reference being had therein to theaccompanying drawings.

The invention relates to boxes especially designed for use as shippingand delivery boxes.

It is the object of the invention to obtain a light, strong, and durablestructure in which the goods can be conveniently packed and secured andwhich may be cheaply manufactured.

To this end the invention consists in the construction as hereinafterdescribed, and shown in the drawings, in which Figure 1 is a perspectiveview of the box. Fig. 2 is a vertical longitudinal section thereof. Fig.3 is an enlarged portion of Fig. 2. Fig. i is an enlarged cross-section.

The sides and bottom of the box are formed of a slat and metallic ribbonfabric woven to bring the slats comparatively close together.

his fabric is preferably formed by first crimping the metallic ribbonsby suitable mechanism and afterward weaving the fabric, which may bequickly done by hand.

The ends A A and the bottom B of the box are preferably formed of acontinuous web which is bent at right angles at the bottom corner, whilethe sides O O are preferably formed of separate sections of the fabric.To strengthen the corners of the bottom, a reinforcing-strip I) ispreferably arranged. inside of the box and secured in the corner formedby the adjoining sides and bottom. The corners between the ends andsides are also strengthened by the vertical posts E, also arrangedwithin the box and having the sides and ends nailed or otherwise securedthereto. The top of the box is strengthened on all sides by weaving in aheavy rail F at the upper edge of each section of fabric, which railstogether form a strengthening-rim to the box. The corner between thesides and bottom in forming f 5 of the metallic angle-strip K, which isarthe ends and bottom throughout their entire length. 6 5

2. A packing-case having the ends and bottom thereof formed of a singlepiece of fabric comprising longitudinal oppositely-crimped thin flatbands or ribbons and cross-slats secured together thereby, sides formedof sepa- 7 rate sections of said fabric having heavy top and bottomrails woven in, the end sections having heavy top rails woven in,- andreinforcing-strips arranged inside the case in the angles between saidends and bottom. 75

8. A packing-ease having the sides and bottom thereof formed of a fabriccomposed of slats arranged adjacent and in close proximity to each-otherand adjacent thin metallic securing-bands having a flat surface andcrimped 80 with square bends to embrace said slats alternately uponopposite sides thereof, the square bends of the bands constituting aflat bearing for the top and bottom of the adjoining slats, and one ofsaid slats being relatively heavier than the remaining slats, all ofsaid slats when assembled being flush upon their inner surface.

4. In a packing-case, the combination with side sections formed ofwoven-slat fabric, of a 9 corner-post extending vertically in the cornerformed by adjacent sides and a metallic anglestrip embracing the outerface of said corner, the end of said strip being slitted in the angle toform separate sections, and said sections 95 being crossed over the endof said post and lapped over the adjacent inner sides thereof.

5. In a packing-case, the combination with side sections formed ofwoven-slat fabric having heavy rails at their upper edges flush with 100the inner face of the fabric and projecting outward, of a corner-postarranged in the angle formed by adjacent sides, a metallic anglestripembracing the outer faces of said corner, said strip being slitted inthe angle at the end 5 to form separate sections and said sections beingbent to pass around said heavy rails, cross the top of said post and lapthe adjacent inner faces thereof, and a metallic angle-piece for thecorner of said heavy rail overlapping 110 said angle-strip.

6. In a packing-case, the combination of side and bottom sections formedof woven fabric, the side sections having a heavy rail adjacent to saidbottom, and said bottom over- 5 lapping the lower edge of said heavyrail, a metallic angle strip embracing the corner formed by said sideand bottom and a longitudinally-extending shoe-strip covering the lowerflange of said angle-strip and secured to 120 by the same nails whichserve to attach said fabric to the vertical posts E. The corner betweenthe adjoining reinforced top rails is further strengthened by anangle-brace I, which 5 may be secured over the strips 0 and d. The

lower ends of the braces H are formed and secured ina similar way to theupper ends thereof, with the exception that the separate end portions 0and f are merely overlapped upon IO the bottom section of the box. Tohold these overlapped ends from accidental displacement, the shoe J,which extends longitudinally of the bottom, is arranged to cover saidends of the strip. Said shoe also overlaps the edge ranged to strengthenthe angle between the bottom and sides of the box and which secures thelatter to the former. This angle-strip has its opposite flange securedto the bottom rail of the sides, and the ends thereof are held in placeby corner-pieces I, which are also, preferably, formed with roundedcorners g for protecting the lower corner of the box.

The top of the box may be formed, if de- 5 sired, by a detachablesection of the same fabric, but preferably is formed, as shown, by thestationary cover L and a sliding cover M. The latter engages withchanneled guides N, secured to the side top rails and extending 3between the posts E. These guides are cut away at one end to formentering-slots it, through which the cover M may be introduced into thechannel of the strip before the cover L is secured in position. Thecover L is then fastened to the body of the case in any suitable mannerand will prevent the cover M from being detached, although the latter isfree to slide in the channels 2 3' represents cleats extendinglongitudinally of the upper face of 4 the cover M, which prevents saidcover from engaging with the entering-slots 7e when slid back under thecover L.

A box thus formed is exceedingly light and strong and is thus especiallyserviceable as a shipping-box. It is also cheaply constructed, for thereason that the metallic ribbons and corner-braces may be formed bymachinery, after which the weaving of the fabric and the assembling ofthe parts may be quickly accom- 5 plished by hand.

What I claim as my invention isl. A packing-case having sides, ends andbottom thereof formed of fabric, comprising longitudinal adjacentopposite crimped flat bands and cross-slats extending longitudinally ofthe same secured together by said bands, the bended portion of saidbands constituting a flat bearing for the top and bottom of the adsaidbottom. 7 joining slats, the upper ends of said flat bands 7. Apacking-case having the sides and betpassing around rails at the topofthe sections, torn thereof formed of a fabric comprising said railsbeing relatively heavier than the slats adjacent and in close proximityto each crossslats,andthe parts when assembled formother, and adjacentoppositely-crimped me- 5 ing a smooth uninterrupted inner surface fortallic bands inelosing said slats alternately upon opposite sidesthereof, the top and bottom slats of the side sections being relativelyheavier than the remaining slats and Woven into the fabric by the bands,which pass over 5 one side, around the upper edge and are secured to theopposite side upon the returnbend.
